this photo belongs to the collection from StuG.Abt. 189
Was there any Knights Cross winners from this unit.
Especially in 1942 Russia as this seems to be the year written on all the other photos.
Many thanks.

Thanks Simon.
I think this photo was war time produced for many stug members.
And thanks for pointing out this great book.
It looks fantastic and i think its worth adding to the shelf !
Many thanks.
